This shit is so hard... This alone will probably make me fail my math test >.>

+TheDkmariolink Yes it is, I hate being in honors class doing this because the way things are weighed are different from regular classes so if i fail one thing, my grade drops a entire letter grade. Then i have finals in two months and this is going to be on it.. I guess I am going to have to bring in 20 packets of lined paper to do my work on.
